1 Introduction
1.4.13

Protection against freezing

The boiler has a built in frost protection programme as
long as the electricity and gas are left switched on.
This device operates the burner and system pump
when the temperature inside the boiler falls to 3°C.
Any other exposed areas of the system should be
protected by a separate frost thermostat.
If the mains electricity and gas are to be turned off for
any long periods during severe weather, it is
recommended that the whole system, including the
boiler, should be drained to avoid the risk of freezing.
Make sure that, if fitted, the immersion heater in the
cylinder is switched off.
If you have a sealed water system contact your
installation/ servicing company as draining, refilling
and pressurising MUST be carried out by a competent
person.
As a safety feature the boiler will stop working if the
condensate drain becomes blocked. During freezing
conditions this may be due to the forming of ice in the
condense drain external to the house. Release an ice
blockage by the use of warm cloths on the pipe. The
boiler should then restart. Contact your installation/
servicing company if the fault persists.
1.4.14

Boilers installed in a compartment or

cupboard

If the boiler is fitted into a compartment or cupboard it
does not require ventilation openings.
Do not use the compartment or cupboard for storage.
1.4.15

Boiler casing

Do not remove or adjust the casing in any way, as
incorrect-fitting may result in incorrect operation or
failure to operate at all.
1.4.16

Condensate drain

The condensate drain must not be modified or blocked.

1.4 .17 Pluming from flue terminal

All condensing boilers produce a plume of water
vapour from the flue terminal. This is due to the
high efficiency and hence low flue gas temperature.
This may increase in wet, damp weather but this is
completely normal and indicates that the boiler is
operating correctly.
1.4.18

Cleaning

This appliance contains metal parts and care should
be taken when handling and cleaning with particular
regard to edges.
The boiler casing can be cleaned using a mild liquid
detergent with a damp cloth, then a dry cloth to polish.
Do not use any form of abrasive or solvent cleaner as
you may damage the paint work.

Maintenance and servicing

For the continued efficient and safe operation of the
boiler it is recommended that it is checked and
serviced at regular intervals. The frequency of
servicing will depend upon the installation conditions
and usage, but in general, once a year should be
enough.
If this appliance is installed in a rented property there
is a duty of care imposed on the owner of the property
by the current issue of the Gas Safety (Installation and
Use) Regulations, Section 35.

in the countries of destination.
